Could it be a historical queen? Let me think. There's a Kara Koyunlu dynasty in the 14th-15th centuries in the Caucasus and eastern Anatolia. Maybe a queen from there? Or perhaps a person from another culture? Also, considering the possible transliteration, maybe there's a misspelling. Alternatively, it could be a title of a document or a book that's available as a PDF. The user wants an informative paper, so they might need information to write their own paper or study this topic.
